About the Airtac SC100 Standard Cylinder SC100X125H
The SC100X125H is a double-acting pneumatic cylinder with a 100 mm bore and 125 mm stroke, built for high-temperature duty. Its Viton (FKM) seals shift the operating range to 0–150 °C, making it suitable for autoclaves, foundries, and hot-process automation where standard polyurethane would degrade.
At 0.5 MPa the piston rod extends with 3927 N of force and retracts with 3681 N. The 25 mm diameter rod and 29 mm adjustable air cushion at each end provide smooth deceleration. The body length A is 188 mm, giving a total extended length of approximately 313 mm. Ports are PT1/2 with an M20×1.5 rod thread.

Where the Airtac SC100 Standard Cylinder SC100X125H Is Used
High-Temperature Process Actuation
Viton seals withstand 0–150 °C, making this cylinder ideal for autoclave door actuation, steam-assisted molding presses, and drying oven conveyors where standard seals would fail.
Heavy-Duty Clamping & Pressing
With 3927 N of push force at 0.5 MPa, the SC100X125H powers robust welding jigs, die-casting extractors, and assembly presses requiring consistent clamping under thermal stress.
Hot-Material Handling Gates
The 125 mm stroke actuates diverter gates and chute flaps on foundry sand conveyors or glass processing lines, where radiant heat demands FKM seal integrity.
Is the Airtac SC100 Standard Cylinder SC100X125H the Right Cylinder?
Choose the SC100 when your application needs around 3900 N at 0.5 MPa. If your load is closer to 2500 N, stepping down to the SC80 (2513 N push at 0.5 MPa) can reduce air consumption and physical size. For higher force, the SC125 delivers 6136 N at the same pressure. The 125 mm stroke is well within the 1500 mm maximum standard stroke for this bore.
To replace an existing cylinder, match five points: 100 mm bore, 125 mm stroke, PT1/2 ports, basic (no accessory) mounting, and the -S magnet option if sensors are used. This model carries the H suffix for Viton seals; ensure the replacement also tolerates your operating temperature. For strokes over 300 mm, consider an external guide to protect the rod from side-load bending.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SC100 Standard Cylinder SC100X125H FAQ
At 0.7 MPa supply pressure, the SC100 bore generates 5497 N of push force and 3681 N of pull force on the retract stroke. The theoretical maximum at 1.0 MPa is 801 kgf.
No. The SC100X125H is a double-acting cylinder and will drift or drop if pressure is exhausted or the directional valve is centered. For load holding without live pressure, add a pilot-operated check valve or an external rod brake.
